Simplifying 4x2 + 26x + -25 = 0 Reorder the terms: -25 + 26x + 4x2 = 0 Solving -25 + 26x + 4x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -6.25 + 6.5x + x2 = 0 Move the constant term to the right: Add '6.25' to each side of the equation. -6.25 + 6.5x + 6.25 + x2 = 0 + 6.25 Reorder the terms: -6.25 + 6.25 + 6.5x + x2 = 0 + 6.25 Combine like terms: -6.25 + 6.25 = 0.00 0.00 + 6.5x + x2 = 0 + 6.25 6.5x + x2 = 0 + 6.25 Combine like terms: 0 + 6.25 = 6.25 6.5x + x2 = 6.25 The x term is 6.5x. Take half its coefficient (3.25). Square it (10.5625) and add it to both sides. Add '10.5625' to each side of the equation. 6.5x + 10.5625 + x2 = 6.25 + 10.5625 Reorder the terms: 10.5625 + 6.5x + x2 = 6.25 + 10.5625 Combine like terms: 6.25 + 10.5625 = 16.8125 10.5625 + 6.5x + x2 = 16.8125 Factor a perfect square on the left side: (x + 3.25)(x + 3.25) = 16.8125 Calculate the square root of the right side: 4.100304867 Break this problem into two subproblems by setting (x + 3.25) equal to 4.100304867 and -4.100304867.Subproblem 1
x + 3.25 = 4.100304867 Simplifying x + 3.25 = 4.100304867 Reorder the terms: 3.25 + x = 4.100304867 Solving 3.25 + x = 4.100304867 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3.25' to each side of the equation. 3.25 + -3.25 + x = 4.100304867 + -3.25 Combine like terms: 3.25 + -3.25 = 0.00 0.00 + x = 4.100304867 + -3.25 x = 4.100304867 + -3.25 Combine like terms: 4.100304867 + -3.25 = 0.850304867 x = 0.850304867 Simplifying x = 0.850304867Subproblem 2
x + 3.25 = -4.100304867 Simplifying x + 3.25 = -4.100304867 Reorder the terms: 3.25 + x = -4.100304867 Solving 3.25 + x = -4.100304867 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3.25' to each side of the equation. 3.25 + -3.25 + x = -4.100304867 + -3.25 Combine like terms: 3.25 + -3.25 = 0.00 0.00 + x = -4.100304867 + -3.25 x = -4.100304867 + -3.25 Combine like terms: -4.100304867 + -3.25 = -7.350304867 x = -7.350304867 Simplifying x = -7.350304867Solution
